Repro steps:

• Start qtcreator
• File / New File or Project...
• General / Scratch Buffer
• Create a line of text like this:

__device_inline uint2 operator/(const uint2 a, const uint2& b)

• Put the cursor before the text
• Press Ctrl-F
• Click the magnifying glass in the find field, choose Use Regular Expressions
• Enter the following regex:

(const (?:uchar|char|uint|int|float)\d\s?(?!&))

• In the replace with field enter the following:

\1&

(backslash, one, ampersand, space)

• Click Replace & Find

Expected the line to be:

__device_inline uint2 operator/(const uint2& a, const uint2& b)

Actual incorrect replacement behavior:

__device_inline uint2 operator/(const uint2 const uint2 a, const uint2& b)

I've noticed several people report variations of this bug without detailed repro steps. Hopefully this time the bug will be fixed.
